The brutal heat wave that has Southwest states in its grip is being blamed for at least one death.

Saturday in Las Vegas, an elderly man was found dead in his home, which did not have air conditioning, the Las Vegas Sun reports. Paramedics say the heat contributed to his death, a spokesman for Las Vegas Fire and Rescue tells the Sun. For the second consecutive day, the temperature hit 115 degrees Fahrenheit in the city.

Now forecasters warn that temperatures, which have also topped 110 in other cities, hit 122 in Palm Springs, Calif., and went even higher in Death Valley, won't be coming down in the next few days. What's worse, they might even go a bit higher. As CNN puts it:

"Civic and emergency officials throughout the Southwest say if there was ever a time to worry, this would be it."

"Temperatures will continue to approach or exceed records underneath an expansive upper ridge anchored over the Southwest and Great Basin. Excessive heat warnings remain in effect for a large portion of California ... Nevada ... and Arizona ... where daytime highs will yet again dangerously soar well past the century mark and overnight lows will barely drop into the seventies and eighties. As the ridge begins to build northward late Sunday and into Monday ... triple digit temperatures will expand north through the Intermountain West and all the way to the Canadian border."

"It feels a bit like somebody is blowing a hair dryer in my face at all times. ... It's hot to the crisp and the sun is absolutely punishing," Kirk tells our Newscast Desk. He's been watching a thermometer that just a few minutes ago was registering 129 degrees.

For the record, the National Weather Service's webpage's latest reading was "only" 119 degrees.
